A new utility shaft at the US Department of Energy's Waste Isolation Pilot Plant (WIPP) in New Mexico has now reached nearly 90% of the way to the underground waste repository depth of 2150 feet (655 ...
An in-depth understanding of the dominant factors controlling soil respiration is important to accurately estimate carbon cycling in forest ecosystems. However, information on variations in soil respi...
Scientists had long believed that the waters of the Central and Northeast Pacific Ocean were inhospitable to certain species of deep-sea corals, but a marine biologist's discovery of an odd chain of r...
Scientists have long believed that the waters of the Central and Northeast Pacific Ocean were inhospitable to deep-sea scleractinian coral, but a Florida State University professor’s discovery of an o...

In general, the type of atmospheric aerosols can be efficiently identified with the characteristics of optical properties, such as Ångström exponent (AE) and single scattering albedo (SSA). ...
Information about hydrological systems and water table fluctuations is important for water management and is needed to assess choices for long-term water management policy. Preferably, uncertainty abo...
Plant water stress can limit productivity and has an effect on plant physiology and canopy architecture. Changes in water status of a canopy can have indirect effects on remotely sensed optical refl...
It is an oft-stated statistic that 95% of the ocean is unexplored, but this number does not expose the full extent of our ignorance about the largest ecosystem on the planet—first because it refers to...
Maybe it’s not such a dog-eat-dog world after all. A clever combination of two different types of computer simulations enabled a group of Illinois researchers to uncover an unexpectedly cooperative gr...
Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar "greening" event--a massive bloom of microscopic plants, or phytoplankton--unfolds each spring in the North ...
The intraterrestrials, they might be called.Strange creatures live in the deep sea, but few are odder than the viruses that inhabit deep ocean methane seeps and prey on single-celled microorganisms ca...
Determination of the sorption-desorption of herbicides within soil profile is one of the first steps in predicting their leaching potential. Batch experiments were performed to evaluate the influence ...
. Experiments comprising sequences of deformation (at 300 or 600◦C) and annealing at varying temperature (700 to 1100◦C), time (up to 144 h) and stress (up to 1.5 GPa) were carried out in...
Benthic marine consumers inhabiting the subphotic zone rely on subsidies of energy synthesized by macrophytes and phytoplankton in the photic zone. The effects of this energy subsidy on the trophic ec...
